nginx: worker process is shutting down

Every time I do "nginx -s reload" I see a process:

nginx: worker process is shutting down

This process never stops even after a long time.

Any idea what cause this issue?

From truss (similar to strace):

kevent(13,{},0,{},512,{0.602000000 }) = 0 (0x0)
kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)
kevent(13,{},0,{0xc,EVFILT_READ,0x0,0,0x20,0x802530068},512,{3.000000000 }) = 1 (0x1)
recvmsg(0xc,0x7fffffffe5a0,0x0,0x80248d068,0xffffffff,0x0) = 32 (0x20)

kevent(13,{},0,{},512,{1.180000000 }) = 0 (0x0)
kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)
kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)
kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)
kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)
kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)
kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)

It keeps looping with: kevent(13,{},0,{},512,{3.000000000 }) = 0 (0x0)

And lsof:
